Options Section

The Options section allows you to hide zero count Summary rows, when included in the output, and determine when to display titles, flags, and footnotes.

  • Display Titles – When this box is checked titles will appear in their places. When unchecked, the titles are hidden. 
  • Display Flags – Flags are symbols displayed in a matrix cell to indicate that a footnote applies to that cell. Flags displayed in a matrix window will be included in data copied to another application using the Windows clipboard, and in exported data files for that matrix. You should uncheck the Display Flags option if you are copying or exporting the data to an application that is not expecting character data. When this option is unchecked, Display Footnotes is automatically unchecked and disabled.
  • Display Footnotes –  Footnotes are displayed in the status bar at the bottom of the matrix window. Footnotes are specific to the page being displayed. A flag, or footnote character, is displayed in the cells to which the corresponding footnotes pertain. Footnotes are used for various reasons, including to describe specific calculations, indicate data sources, provide an explanation for empty cells, and show the results of significance testing. If a test is performed, the footnote is displayed in the status bar regardless of whether or not any cells on the page contain the footnote's flag character. The median survival time is noted in a footnote in a Survival results matrix.
